W Wm W I? av wentpz To all whom it may concern: Be it known that I,MYBON Free, a citizen xof the United States, residing at Central Falls,in the county of Providence and State 5. of Rhode Island, have inventedcertain new And useful Improvements in Brushing-Ma- -'-..&chines forLoom-Harness, of which the fol- "lowing is a specification. 1' Minvention relates to im rovements in 101131118 machines for loomarnesses, and .the object of my invention is to provide a I rushingmachine in which paired revolving l hrushes are provided with areciprocating movement and also made to alternately ap- 31 la-tproachand se arate from each other by an I i tagging and c osing movement, sothat the ii the harness is always brushed in the .iaame directionregardless of the speed at which the brushes revolve. I accomplish "2o.";.,this object by the mechanism shown in the p accompanying drawingsin which e 1 is a vertical section of the machine through line X-X ofFig. 3. Fig. 2 is a ,plan view of the machine. Fig. 3 is a verti- "mlfront elevation. Fig. 4 is a detail of the adjusting mechanism. Fig. 5is a detail view of portions of the device illustrating a more fully thebrush operating and adjusting 1 Fig. 6 is aview of the cam de- -wmached.

G, Fi 2, is the driving-pulley having a long hu g upon which are mountedthe gears 1 and 5; from 1, motion is communicated by the trains of gears1234, 1 2'34, to the revolving brushes F-F. Gear 5 through the medium ofgear 6 also drives the shaft M on which is mounted the crank m, Fig. ,1,the shaft being 'ournaled through the members DD, D This crank isslotted for the adjustment of the crank pin m as shown at m in Fi 1,which operates in the slot S of the mem er B. N is a cam fixed upon theshaft M and provided with a slot n, and communicating reciprocatorymotion by .means of the bell crank OO, the rock shaft d on which saidbell crank O-O is fixed, and the quadrant ears e-e, to the arms EE. Thechanne 'n in the cam N is concentric with the shaft M for nearlyone-half of its course and also concentric with the shaft M throu hnearly the other half of its course, one of t e concentric courses beingof a greater radius than the other course, the terminals of the coursesbeing united by relatively curved portions as shown at n in Fig. 6. Bthis means as the shaft M is rotated the ro ler o of the crank arm 0-0will be caused to travel nearly one-half of its course in one position,and then suddenly be moved outward or inward, as the case may be, andtravel the remainder of its course in that osition. Thus as the camrotates the brus es FF will operate close to the harness during themovement of the carriage frame in one direction, and be thrown outwardaway from the harness during the return movement of the carriage, as w'1 be obvious. H is the harness upon which the brushes operate. Thedriving pulley and the various gears, as well as the rushes with theirsupportin arms, including the bell crank lever O- and the cam N, aresulpported by and movable with the carriage D'D The shaft M is connectedby a universal joint M with a worm and gear on the end of the frame workof the machine to operate a feed-motion for feeding the harness throughthe machine. This mechanism is not shown, since any suitable feed-motionmay be used to feed the harness regularly through the machine.

The pressure of the brushes FF upon the harness is adjusted b the deviceshown atthe to 'of Fig. 1, an more in detail in Fig. 4. etween the twoupper arms EE and firmly attached to these arms is a bar P shown insection in Fig. 1 and having a lug p slotted at p as shown. The portion0 oi the bell crank is forked at its outer end and provided with avertical screw Q turning reely in the limbs of said fork being heldtherein by nut g. The screw Q is provided with a nut q having radialpins rr fixed thereon. These pins engage the slot in the lu p, and asthe screw Q is turned the arms /-E' are raised or lowered with referenceto the member 0' oi the bell crank, while E -E are simultaneously movedin an o posite direction, and thus through the uacli'ant gears e-e' thedistance between and F is varied at will. This ad'ustrnent also allowsthe wear on the brushes -F to be taken up as occasion re uires.

In Fig. 2, 3, is shownrols u for applying" varnish, oil or whateversubstance or 'gment it ma be desired to apply to the arness'. Thewermost roll it operates in a pan U containing the substance to beapplied to the harness. In these views is also seen a pair of rollers 6dis d between the rollsa and the brushes F, the function of which is toremove any surplus dressing cg; slice! by the rolls a. The rolls 6" mayriven in any suitable or desired manner from the rolls e which it is notbelieved necessary to illustrate, as, it will be obvious that the rolls6 may be ed with without in any manner interfering with the operation ofthe device. As illustrated in Fig. 2, the rolls to are driven by cars4", 5", the former mounted on a shaft not shown) which carries a pulley3 to receive a drive belt 2 An endless chain w, is operated by themachine and embodies two series of hooks W one series on each side ofthe frame (see Figs. 1 and 2). The harness fibers or strings are carriedby these hooks W of the chain w, and are k t tight by the tension of thetension lever X ig. 1). The two arms o a of this lever are separate, andare geared (not shown) in the same manner as the arms E, E, so that thet or upper ends thereoi move outwardly as t e lower end of the tensionleverA" ispnlled by the coil A.

When the harness is affixed to t e endless chain or and motioncommunicated to the latter, the harness strings are drawn beoil, orother substance thereto, the rolls 6 removing an so his substance 'or tothe harness reoc ing t brushes F ter act upon the harness to impart thedesired finish thereto. The operator removes the finished harness as thesame emerges from the brushes F, F and adds the harness to the chain onthe opposite side of the machine without ing thelattor.

b mthedrawings that the upon the brushes F-F' are not uniarrangedinascries-ofstrips,pmllelwith which lat- 1 1 attached to saidcarriage and provided with a with the crank pin fixed the revolution ofthe shaft M causes the reciprocation of the carria by means of the slotS and the crank and crank pin ml-m. The various members attached to thecarriage DD, I)-D, etc,

bell crank O-O' and the c--e-, the revolvin brushes to come together aruptly at the be innfi of 1 one movement of the carriage Dl), a toseparate abruptly at the end of that moveone direction by the brushesregardless the axes of the two cylinders. The reason I for this is thatin practice I have found that a su erior finish is given to the harnessby the successive stri s of bristles on one cylinder to alternate witthose u on the I other cylinder in their contact with t e harness, asshown in F 1; that is, the harness is not touched by t e bristles of thelower cylinder at the instant it is being brushed by those of the uppercylinder; but strips of the bristles of the upper cylinder alternatewith those of the lower cylinder in their contact with the harness thusgiving a more yielding contact than would be the case if the bristlesworked in direct 'tion to each other. The alternation ol the strips ofbristles is maintained by the respective trains of gears I-2'-$, 1-23',etc.

As the driving pulley revolves it aho causes the revolution of the cam Nand the shaft M to which is attached the crank m m. As the member B isthat is to say, the uprights D-D, the

qusdrant arms E-E and the revolving brushes F-F, with their respectivetrains oi gears reciprocate simultaneously with the carriage DD, D'D.

By means of the symmetrical cam N, the uadrant gears F' are made in thement so that the harness is brushed on speed of their revolution.

By means 04 the endless chain or the brushing process is continuous, theharness passing side wise through between the brushes, permitting theoperator to remove the finrshed harness colt and add the unfinishedharness upon the opposite side without st oppm' g the machine.
